Dense Fog

Some really thick fog developed this morning in areas around the Sioux Falls metro and visibilities at times are near zero. Even though many areas are seeing some lower visibilities because of fog this morning, the really dense clouds have set up shop right around Sioux Falls. Take a peak at a current surface map. The number I have circled represents the current visibility in miles.

Here is a visible satellite image of what the fog looks like just after sunrise. Notice a sharp edge to the blob of clouds hugging the surface.Keep in mind that over 700 people are killed in the U.S. every year in car accidents because of dense fog where visibilities are a quarter mile or less. This is from a 2001 study. The main factor in those crashes is speed. So the best thing you can do if you are traveling this morning is to slow down. Don't become a statistic!!
